Linear Technology is offering the LTC3892: a high-voltage dual-output synchronous step-down DC/DC controller that draws only 29µA when one output is active and 34µA when both outputs are enabled.

The 4.5V to 60V input supply range is designed to protect against high voltage transients, ensuring continuous operation during automotive cold crank and to accommodate a broad range of input sources and battery chemistries.

Each output can be set from 0.8V to 99 per cent of VIN at output currents over 20 amps with efficiencies as high as 96 per cent, making it well suited for 12V or 24V automotive, heavy equipment, industrial control, robotics and telecom applications.

The LTC3892 is available in a 32-lead 5mm x 5mm QFN package and the LTC3892-1 is available in a 28-lead TSSOP package. Four temperature grades are available, with operation from -40 to +125°C for the extended and industrial grades, a high-temp automotive range of -40°C to +150°C and a military grade guaranteed from -55°C to +150°C.
